GSoC Status Update - (Mid-term Evaluation)

[Sarthak Bhardwaj]

Hello everyone,
Here is a status update on the GSoC project:
1. First version of the regression script is done from my side and
submitted for review.

2. The integration for the script in the CI is complete and submitted for
review.

3. macOS builds for Autotools and meson have been added and submitted for
review.


What I am currently working on:

1. Since the integration is complete, I will focus on improving the layout
of the generated web pages.

2. Adding image comparison functionality to the website.


(Note that due to worsening monsoon we are experiencing severe floods in
Himachal
,
so that could cause a little delay to the project, I will try my best to
create a useful website within the first week of August.)

Freedesktop.org down

Re: Compile FreeType Demos with static linking

[Sarthak Bhardwaj]

On running "make devel" in freetype source it says something like "make:
Nothing to be done for 'devel'". So, I presume static linking is not
working properly right now in autotools ...

Compile FreeType Demos with static linking

[Sarthak Bhardwaj]

Hello Werner Alexei,

I just wanted to know if it is possible to compile the FreeType demos with
static linking?

GSoC Report

[Sarthak Bhardwaj]

Hello Everyone,

 Here's a status update on the Regression Testing GSoC project:


*What I have done so far:*

1. Modified ftlint to output glyph md5 hashes for fast testing

2. Created a script for regression testing, that can be run locally or in CI

 https://gitlab.freedesktop.org/freetype/regressiontest/-/merge_requests/1

Almost finalized only a few things need to be improved.

*What I am working on:*

1. Finalizing the CI script

2. Integrating the script in Freetype's CI

3. Adding CI for macOS and iOS (Migrating azure to GitLab)

This stuff should be in MRs by the weekend. Since FreeType, now has CI for
windows and Linux, I believe I don't need to port their azure config


*What I will be working on soon:*

1. Beautifying the generated web pages and adding functionality (image
comparison, etc.)

2. Making the script more robust against unexpected inputs (font failing to
render, etc.)

This will be completed by the end of July.

Thanks
Sarthak Bhardwaj

Re: [Freetype-devel] Difference in rendering

[Sarthak Bhardwaj]

Hello Suzuki,

I believe you misunderstood me, I meant I have a program for highlighting
differences in images, I wanted to test what would happen in a regression
scenario, so wanted to know how to create a regression/difference in
freetype's rendering output.

Thanks

Hello,
I was a little confused about, What file should I modify in the FreeType
source to produce a small but noticeable difference in rendering. Please
share your suggestions

Query regarding generating MD5 Hashes of rendered gyphs

[Sarthak Bhardwaj]

Hello Werner,

While trying to generate MD5 hashes of rendered glyphs, I came across this
discussion:
https://lists.nongnu.org/archive/html/freetype-devel/2017-03/msg1.html

I tried compiling freetype with FT_DEBUG_LEVEL_TRACE defined and set the
env variable FT2_DEBUG to bitmap:3, but ftgrid doesn't seem to output any
hash. Can you please tell me what I am missing, will be glad if you sort
this query out for me.

Thanks,

Yes I have seen his work and  we have also discussed the various parts and
aims for this project that need to be accomplished. I have also done some
work on that but was little confused that whether it is allowed or kind of
legal to send MR before the coding period or not. But I think now there is
no such issue with that. We will try our best to have this project's
discussion in a constructive way, will for the best:)

Yes, actually I have done it yesterday itself, sorry for not informing you
as I have stated the reason I was very busy, and it is working fine for me,
capturing ss from [P] and aborting the process with [esc] key or [q]
and.., and the snapshot is getting saved in the freetype-demos folder
itself naming ftview.png and ftgrid.png in parallel to the command that has
executed, and every time these are updating whenever I run ftview or ftgrid
respectively.
I am sharing the generated pngs...

I am sorry for the confusion, I mean to say that as Alexei have suggested
us to run it directly ,by not using Xvfb and capturing the screenshot by
pressing simply [P], that is giving us the .png file saved in same
directory.
 I think this is what you use to test it in a manual way.

my question is that as the goal is to have a CI script for the gitlab
instance of 'freetype.org' thats gets called automatically and will process
the whole thing of checking graphical difference.
So do we need to follow up with the same technique that is by running it
directly and capturing screenshots manually all the time or we need to have
some changes in xvfbRunAndScreenShot itself to make it more efficient, or
do we need to swap out the xvfb commands with some other taking xvfb out of
the way..

Ok got it, but still confused over the thing that whether we have to follow
the traditional method all the time i.e.  xvfbRunAndScreenShot, and check
some enhancement  in it itself,
or we have to do it manually all the time or student need to figure it out
by themselves a suitable substitute of it?
Because I think this project is all about automating all the process
therefore it seems more likely to me that we should not use manual aspect
all the time, rather will find a way that will work well...
please correct of I am getting it wrong, and do share your valuable
instructions,
   Thanks in advance

Testing framework

[sarthak bhardwaj]

hello mentors,
I had found the same problem as Aman is facing some days before actually, I
forgot to intimate about this thing earlier,
inside test-font.sh, there is a function written xvfbRunAndScreenShot, it
will show error and only blank png's will be generated, as far as there is
no  ../freetype2-demos/bin/ftgrid directory found in our demos program, and
there is no branch in demos for GSoC's Gregs works. It will only work when
ftgrid file will get merge to the demos repo.
I have found the solution and is running that way but if it is working
without the ftgrid file please let me know the way.

thanks,

testing framework GSoC

[sarthak bhardwaj]

hello,
I just want to comment on Aman's query regarding running the framework
locally, for running it locally

   1.  firstly you need to follow some instructions which are given on this
   page -
   https://lists.nongnu.org/archive/html/freetype-devel/2020-07/msg00147.html
   .
   2. one thing that I was also missing at first that you have to change
   the name of the cloned file from 'freeType' to 'freetype2'.
   3. make sure to install all required stuff and you should have
   test-fonts that contain .ttf files inside your home.

I think this will sort your problem as far as i have understood it :)

Thanks
Sarthak

Hello mentors,

Do share your remark over this or can I proceed according to what he have

and the most ambiguous thing in current is -  whether i have to make
proposal for the entire thing, or just for the subproject he suggested me
to do so.?

See I have no issue with it, either way, I just want to work, whether it
will be on a full project or any subproject from this project itself, I
agree that the engagement (so far seen) in other projects are likely to be
less and it can be an option.
and if this is the case what you want me to do to separate our working
domains will totally be decided after the mentor's remark over this,
whatever they will say I am ok with that thing.
Well commenting about the motive of GSoC, it's more about getting students
engagement towards the OSS so that the number of contributors can be
increased, and can get some experience in OS development on a good level.

Hi Alexei,
Thanks for the feedback, TBVH I have not gone so far researching about
image generation though i got only basics, as  I was more and more focusing
on migrating the integration tool servers and came across many different
stuffs for setting up the roadmap for migration as well as improving UI,
But again thanks for your useful feedback, I have marked your words and
will surely update the draft ASAP, and if you find any more improvements
please give intimation.

Develop a test framework for checking FreeType's rendering output

[sarthak bhardwaj]

hello,

I want suggestions regarding generating HTML pages depicting the
comparison, as this project wants to add some good UI, or can say we need
something more functional and reflexive than the current one.

I think using something like Jekyll or HUGO will be a plus, as the Jekyll
plugin is a static website generator with great support for GitLab Pages
and makes the build process simpler. Jekyll. Plugins Support takes HTML
files and Markdown and creates a completely static site based on your
preference of layouts. One can easily configure most Jekyll settings, for
example, your website’s plugins and theme, by editing your _config.yml
file. The same goes for HUGO. So can it be an option or not?

 If it will work it can definitely resolve the problem of having a
sophisticated UI, otherwise bootstrap and materialize CSS should be another
approach and they will work for sure...

And for the proposal, do FreeType demand any specific questions to be
answered in the proposal, as some other orgs do, or it should be kept
general i.e. as mentioned in GSoC guidelines
<https://google.github.io/gsocguides/student/writing-a-proposal>.

I think I could be explained earlier in detail from my side, sorry for that
if I am not getting it wrong, In this project( as far I have observed) the
sequence should be like that -


   - firstly we need to set up continuous integration services compatible
   with GitLab.
   - After setting up we need to add compilation and some desired
   functionality tests to our code, along with these services we can use a
   custom test harness(It is a collection of software and test data
   configured to test a program unit by running it under varying conditions
   and monitoring its behavior and outputs. ... Test harnesses allow for
   the automation of tests.) to check for compile errors.


This is my opinion about it, I might be wrong, Please correct me if I have
misunderstood the thing, and do suggest your opinion about this

Develop a test framework for checking FreeType's rendering output - GSoC Project

[sarthak bhardwaj]

hey Werner,

In the last few days, I have come across Freetype's Documentation and
previous contributions on this project(GSoC), what I have observed is-

   - Most of the things are already implemented in it, which means we don't
   need to start anything from scratch we just need to do some quick additions
   and omissions to the code


   - Coming to the CI segment as I read Greg's work
   and I can
   see the azure checks running on Github, we just need to port azure configs
   he wrote to be compatible with GitLab's CI, as it is commented very well
   it's not gonna be very hard to do so.


   - There should be some custom test harness in concurrence with checks
   for more accurate results.

   - We can add some better User Interface by using some javascript,
   Bootstrap(mainly CSS part), and can add some more functionalities or can
   say features in it.

   - We can switch to some better comparison tools as bmpcmp clips generate
   layers of mouse-over action

this is what I have observed as the primary goals or can say what is
expected from this years' projects is, as this is what I think is imp,
please correct me if I have mistaken somewhere, and kindly share your views.

Hello,

As directed by you i have tried all the things and i think I have gathered
some good amount of info,

As far as CI part is concerned which was earlier not compatible with
Savannah, but as whole codes moved to gitlab, now we have probably multiple
ways to implement that, either we can use repo mirroring by using Azure
pipeline for CI (as it provides marketplace of plugins for integrations
into pipelines and allows caching proxy of external repos)
 or we should simply write what is compatible with gitlab's CI.

So suggest me what should be better approach so that i will make my mind
accordingly and will start reading about the same.

Thanks in advance

Develop a test framework for checking FreeType's rendering output - GSoC Project

[sarthak bhardwaj]

Hi,
I am Sarthak Bhardwaj, a junior-year student currently pursuing my B.Tech
In Computer Science from National Institute Of Technology Hamirpur, India.

I am interested to work on this year's GSoC Project - "Develop a test
framework for checking Freetype's rendering output".

 So I have done some googling from my side and it helped me to make many
things clear, I have also read some of last year commits and mailing list
archives of Greg Williamson, who was engaged in last year's Project which
was on  "Add/Improve Freetype Testing Framework", I found it very useful
and it helped me to get a very basic overview about this project.

Please guide me on whether my learning approach is correct or what should
be my roadmap for getting some good knowledge on these things related to
this idea and the codebase also.
